Study On Interaction And Self-Stability Of Superconductive Flux-Pinned Connection

Spacecraft technology is attractive and intriguing in a number of countries, the connection of spacecraft take very important role in them, there are still complicated attitude control and high-cost, as well as high-risk due to traditional technology, although a variety of achievements are obtained using conventional way. For sake of limited disadvantage, the novel method is necessary and eager for related technology. The investigation of the connection of spacecraft technology based on flux-pinned effect is proposed in this thesis, since it not only exhibits self-stable and noncontact, but it also has the ability to resist disturbance. In addition, a kind of reconfigurable architecture with control strategy is imagined.In theoretical analysis, this thesis proposes the improved image dipole model by adding a new proportional constant and the vertical component of flux-pinned interaction is obtained based on the novel model. In addition, the feasibility of flux-pinned joints is demonstrated based on the novel model.In experimental analysis, the experimental data performed in my simple self-experimental table is collected under distinct conditions, which is used for contrast with theoretical formula. The consequence shows the precise model corresponds to the experimental data well, while the simple model has bad performance, where the reason is described in this thesis. The experiment with the intention of hysteretic and relaxing effect of levitation force is also performed,which shows the levitation force appear increasable instead of decay in the second descending process and the relaxing effect has two different trends that one is that the force only decay and the other is that the force would decrease initial with decay later.In the investigation of flux-pinned system consisted with high-temperature superconductor and permanent magnet, potential interaction and damper model is addressed based on spring and damper model since the flux-pinned interaction is considered as a kind of special potential interaction, which can effectively deal with the complex flux-pinned system. Through Lyapunov stability, the self-stability of flux-pinned system without gravity is demonstrated based on two models. The active response with flux-pinned system is simulated in numerical methods and the demonstration of self-stability is further completed in numerical ways.
